新建Spring boot项目：

1.编写domain类

package com.example.domain;
public class Phone {
    private String phoneName;
    private String phoneNumber;
    public String getPhoneName() {
        return phoneName;
    }
    public void setPhoneName(String phoneName) {
        this.phoneName = phoneName;
    }
    public String getPhoneNumber() {
        return phoneNumber;
    }
    public void setPhoneNumber(String phoneNumber) {
        this.phoneNumber = phoneNumber;
    }
}

2.编写controller类

 

package com.example.controller;
import java.util.HashMap;
import java.util.Map;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping(value="/phone")
public class PhoneController {
    
    @RequestMapping
    public String index(){
        return "Hello World!";
    }
    
    @RequestMapping(value="/getmap")
    public Map<String,String> getMap(){
        Map<String,String> phoneMap = new HashMap<String,String>();
        phoneMap.put("name", "apple phone");
        phoneMap.put("money", "5000");
        return phoneMap;
    }
}


3.pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.example</groupId>
    <artifactId>demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>demo</name>
    <description>Demo project for Spring Boot</description>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

4.如果你的应用涉及到数据库，需要在pom.xml中增加对数据库服务的访问包。

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>
        <dependency>
          <groupId>mysql</groupId>
          <artifactId>mysql-connector-java</artifactId>
        </dependency>

5..配置application.properties文件

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/demo_test
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=root
